THE MATH
Whole-house rewiring cost formula
Total = area × rate × age + labor + outlets + panel + permitsCable and rough-in materials run ~$1.75/sq ft; pre-1970 installs add 30%. Each outlet or device adds ~$35 in materials. Panel and labor are priced separately to avoid double counting.
PRACTICAL EXAMPLE
1,800 sq ft, 1970-2000 wiring, 15 outlets, 30 hrs, new panel
Materials = 1,800 × $1.75 × 1.1 = $3,465. Labor = $1,800. Devices = $525. Panel = $2,000. Permits = $500. Total ≈ $8,290.
